CVE-2026-34742 2 Lfprojects, Modelcontextprotocol 2 Mcp Go Sdk, Go-sdk 2026-04-07 8.1 High
The Go MCP SDK used Go's standard encoding/json. Prior to version 1.4.0, the Model Context Protocol (MCP) Go SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication with StreamableHTTPHandler or SSEHandler, a malicious website could exploit DNS rebinding to bypass same-origin policy restrictions and send requests to the local MCP server. This could allow an attacker to invoke tools or access resources exposed by the MCP server on behalf of the user in those limited circumstances. This issue has been patched in version 1.4.0.
CVE-2013-0270 2 Openstack, Redhat 2 Keystone, Openstack 2026-04-07 6.5 Medium

CVE-2023-53524 1 Linux 1 Linux Kernel 2026-04-06 7.8 High
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_buf An integer overflow occurs in the iwl_write_to_user_buf() function, which is called by the iwl_dbgfs_monitor_data_read() function. static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count, void *buf, ssize_t *size, ssize_t *bytes_copied) { int buf_size_left = count - *bytes_copied; buf_size_left = buf_size_left - (buf_size_left % sizeof(u32)); if (*size > buf_size_left) *size = buf_size_left; If the user passes a SIZE_MAX value to the "ssize_t count" parameter, the ssize_t count parameter is assigned to "int buf_size_left". Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a negative number, so "*size" is assigned "buf_size_left" and goes into the third argument of the copy_to_user function, causing a heap overflow. This is not a security vulnerability because iwl_dbgfs_monitor_data_read() is a debugfs operation with 0400 privileges.
CVE-2025-26597 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2026-04-06 7.8 High
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.
CVE-2025-26595 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2026-04-06 7.8 High
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
CVE-2023-53521 1 Linux 1 Linux Kernel 2026-04-06 7.1 High
In the Linux kernel, the following vulnerability has been resolved: scsi: ses: Fix slab-out-of-bounds in ses_intf_remove() A fix for: BUG: KASAN: slab-out-of-bounds in ses_intf_remove+0x23f/0x270 [ses] Read of size 8 at addr ffff88a10d32e5d8 by task rmmod/12013 When edev->components is zero, accessing edev->component[0] members is wrong.
CVE-2006-10003 1 Toddr 2 Xml::parser, Xml\ 2026-04-04 9.8 Critical
XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack. In the case (stackptr == stacksize - 1), the stack will NOT be expanded. Then the new value will be written at location (++stackptr), which equals stacksize and therefore falls just outside the allocated buffer. The bug can be observed when parsing an XML file with very deep element nesting
